they're the same person right? Kelvin said he was a "spook" (CIA operative)

so why the different first names?

I liked the finale a lot. nice revelation: Gale is their boss, but is he the "HIM" that Zeke was talking about in Claire's flashback?

But the zinger of them all: THE OUTSIDE WORLD. Desmond's girlfriend hired some russians to monitor electromagnetic disturbances to find him? what??? and they found some?!!! wow. up till now we haven't seen anything about the outside world except in flashbacks. that was way cool.
